The supply chain is gone:
To avoid any gap in providing independent repair spacewalks as a safety contingency for the space station, Congress, NASA and the ISS partners should evaluate the option of postponing the launch of STS – 135 until more external fuel tanks and other parts can be built to support additional shuttle flights in 2012.
2012? What are they smoking?
It would be at least two years, probably three, before they could resurrect the tooling and manufacturing needed to do this, and it would cost billions of dollars that NASA does not have, and isn’t going to get. Meanwhile, we’d have thousands of workers sitting around, forgetting how to launch safely. This is just crazy, and disappointing, considering the sources. Do they really so completely lack imagination that they can’t conceive of ways to do EVA and ISS repair and maintenance with what is currently coming on line, and not relying on an unsafe hyperexpensive vehicle? This is the product of emotion, not thought.
[Update early afternoon]
I have a sort-of-related bleg. I’m working on an article about the false lessons learned from the Shuttle, and how they’re continuing to screw up space policy. Suggestions in comments are appreciated. The first and most obvious one is that it proved reusables don’t reduce cost.
